Tables? Primary keys? What is that? We don't use those words in
polite company here, those are dirty little implementation details
best left in the dark corner of the closet. You have one instance
(object) each of two entities (classes). Object A knows about (has a
relationship to Object B. Does Object B know about Object A?
I am able to properly insert both sets of information into
their respective tables.
That is EOF's job. Insert into tables? Who worries about low level
details like that?
However when I go to view the information from inside a web page
the information that should be displayed through the relationship
does not appear.
Well, OK. Probably you have done something wrong. How are you
creating the two objects? How are you establishing the relationship
between them (telling A about B and / or B about A)? What does your
code look like?
What is even more confusing is when I rebuild the project the
information that didn't appear before appears now. I've tried
reconstructing all my objects (i.e. the display group, the entity
objects etc...) but that doesn't seem to help.
Sounds like you are relating the objects incorrectly. You are not
actually, shudder, touching primary keys with your bare hands, are you?
